Official DescriptionEdit

My name's Leo and I've got three rowdy brothers who always give me a hard time, but I keep them in line... usually.
Master Splinter picked me to lead because I eat, sleep, and breathe ninjutsu. Not that my brothers aren't good. I'm just better. and Raph, please follow my plans and instead of being "impatient" all the time. I know that your always like that but PLEASE be patient with me. thanks dude!



Leo is an emerald green colored mutant turtle with light indigo eyes. He wears a blue mask where the tails length range between Donnie and Mikey's. Like Raph, Leo doesn't have much changes to his physical appearance like all his previous incarnations, except for the fact that his green skin is slightly darker than the others. His height ranges between Raph and Donnie's. He is lean, looks more mysterious and is handsome and or charming.


Like the intro states he is the leader and makes the commands. Leo is the most serious and disciplined out of all the turtles and is of course their leader. He has a lot of responsibility on his hands, which can sometimes overwhelm him. He watches a T.V. Show called "Space Heroes" and wants to be just like the captain he sees on T.V. Overall, Leo acts as a big brother to the turtles and as a teacher's pet to Master Splinter. He was chosen to be the leader because of his willingness not by his skill.

Leo is the most mature out of all his brothers, aside from Donnie, always acting like a guide and sometimes even a parent to his brothers. He is very protective of his siblings and is willing to do anything for them. Unlike all his incarnations, Leo is somewhat a sci-fi geek, aside from Donnie. Though he's more of a techy geek. Leo loves "Space Heroes" and tends to try to be like the hero on there, much to the annoyance of his brothers. He also tries too hard to act like a hero and says cheesy lines, which annoy Mikey, Donnie and Raph.

He is the wisest, most expirenced and balanced of the team and demonstrates many important qualities needed in a leader. Leo does his best to lead the team, but he sometimes second-guesses himself and his constant sibling rivalry with Raphael can cause problems for the team and puts a strain on his relationship with Raph. He often tries to compare himself to the main character of "Space Heroes," Captain Ryan, which annoys his brothers.


Leo is an extremely skilled martial artist and swordsman. His weapons of choice are a pair of katana blades which he uses in a traditional niten-ryu style. He has a good line of defense, and is the best at planning strategies. He is pretty strong when it comes to defense and counter attacks and he is mainly a well ballanced ninja in terms of strengh, speed, agillity, and intelligents.

Like his brothers, Leo is stealthy, can hide in the shadows, sneak around without being detected and use hand to hand combat like a real ninja.


Leonardo and his brothers were once ordinary turtles: when they were infants, they were adopted from a pet store by Hamoto Yoshi (Splinter). When their soon to be father walked passed a strange man, a kraangdroid, he felt something odd about him and followed. Unfortunately Splinter gave away his position when he accidentally stepped on a rat's tail. The Kraang found him and attempted to kill him, but Splinter fought back hard. In the end, the Kraang dropped the canister of mutagen causing the turtles and Splinter to mutate. Splinter came in contact with a rat last, thus mutated into a rat, While he and his brothers, after coming in contact with Splinter when he was human, mutated into humanoid turtles. Splinter knew they would never be accepted in their urban society, so he took them to the sewers, made a home down there, and made the four turtles his children. Knowing the world would be dangerous and there would be a time where they want to explore the outside world, Splinter trained the boys in the art of Ninjitsu. He and his brothers were named after great Renaissance artists from a book Splinter fished out of the storm drain.
